To all whom t may concern:

Be it known that I, Gaza HonvATii, a citizen of the United States of America, residing at Detroit in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Bearings, of which the followingis a specification, reference being had therein to the accompanying drawi gs. i In the mounting of grinding disks which turn at high speed and of other like devices, it is essential that the spindle or shaft on which they are 'secured be as firmly supported as possible in t-lie bearing to avoid chatterin and at the same time turn freely and there y lessen the-danger of burning of the bearin or cutting of the journal itself. It is a so desirable that the exterior of the Abearing present as little obstacle as vpossible to the use of tools around it. Irovision must also be ina-de for taking up wear and thereby avoid jumping or chattering of the spindle in the bearing.

This invention relates to a bearing, and more especially to means for takin up slack in the bearing, for accurately a justing the parts to tirml support the running parts and to a'ord su cient lubrication.

The invention consists in the matters hereinafter set forth and .more particularly pointed out in the claims.

' In the drawings, Figure 1 is a view in longitudinal section through a bearing that embodies features of the invention, and Fig. l2 is aview in cross section taken on or about linejll--ll of Fig. l.

As herein shown an outer boss or casing 1 is accurately fitted at one end to receive a tapered bored bushing 2 with end flange 3 abutting the end face of the casing. A spinv dle4 has a tapered portion or section 5 adapted to t the conica-l bore of the bushing 2; A

cylindrical portion 6 of the Spindle is rotatable in a lining sleeve 7 secured in a barrel 8 whose inner end portion has sorewthreaded engagement with an inner peripheral rib 9 vof the casing and Whose main body portion 10 is turned to accurately fit in a corresponding part of the casing. The bore of the casing between the approximate ends ofI` the member 2 and Ipart 8 is enlarged as a con venient oil chamber to which access is had through a duct closed by a removable plug 411 4an oil ring 12in the chamber loosely encircling the spindle and distributing oil thereover. A thrust ring 13 is secured against the end 'of the lining 7 iii a counterbored recess of the barrel 8 which is of greater' diameter than the louter diameter of the ring. Preferabl the thrust ring is of hardened tool stee or tlie like and abats the flanged portion 14 of a sleeve 15 journaled on a reduced portion 16 of the spindle. A thrust nut 17 is screwthreaded into the outer couiiterbored recess of the barrel 8 and has a lining ring 18 abutting the outer face of the flange 14. Adriving pulley 19, gear wheel or thelike may be secured by, means of the usual'cap nut 20 on the spindle in abutment with the outer end of the member 15 but clearing the member 17.

A shield 21 on the spindle encircles the part 3 as a dust protector and the barrel 8 is provided with Spanner holes 22 or the like for read application of a turning tool or wrench. transverselydisposed binding stud 23` in the casing laterally hollowed to bear against the eriphery of the member 8, may be used to c am the latter in adjusted pocsit-ion by means o a nut 24 -on its outer 80 en By this form' of construction a very long, substantially continuous bearing is obtained which is practically dust roof, which is readily lubricated, and wliic maybe taken upto compensate for wear by rotation of the barrel 8, thereby drawing the spindle to seat in the tapered portion of the member 2. 'Ihe outer clearance afforded the thrust rings prevents the latter from hindering the true' 90 centering of the spindle which de ends merely upon the proper bearn bus ings for support. As the exterior of t e bearing has no projecting adjustin or ca screws, the bearing `does not inte ere wit the use of tools close to it, this arrangement making it exceptionally fitted y for a grindin or milling attachment to a lathe or the ike Furthermore one movement of one member, the barrel, effectively takes up the bearing without the necessity of. setting up a number of clam i'ng bolts such as are commonly use /for this purpose. i

\ viously, changes in the details of construction ma be made without departing from the spirit of in invention and I do not care to limit mysel to any particular form or arrangemento'f parts. i

I claim,

-1. The combination with an outer casing,

' of a taper bored bushing secured in one thrust nut screwthreaded into the recess of the barrel Aagainst the outer face of the collar and a clampingnut on the reduced end of the spindle.

2. The combination with a casing of a taper bored bushing secured in one end portion thereof. and provided with an end flange abutting the casing end, a take up barrel having an inner end portion screwthreaded into the middle portion of the casing, and a cylindrical body portion journaled in 'the casing and a counterbored outer end, a thrust ring seated in the counterbored end portion of the barrel, a'spindle extending through the casing and having a tapered portion` journaled in the bushing. a body portion journaled in the barrel and a reduced end portion extending through the counterbored recess of the barrel, the resultant shoulder of the spindle being in substantial. alinement `with the bearing face of the thrust ring, a thrust sleeve journaled on the reduced portion of the spindle and provided with an enlarged inner end portion bearing against the thrustring and spindle shoulder, a thrust nut screwthr'eaded into the outer counterbored recess of the barrel and adapted to bear against the outer face of the enlarged end portion of the thrust sleeve, and a retaining nut on the outer reduced end portion of the spindle.

3. The combination with a casing, of a taper bored bushing secured in `one end portion thereof, and provided with an end flange on the sleeve abutting the casing end, a take up barrel provided with a recessed outer end an inner end portion screw threaded into the middle portion of the casing and a- Cylindrical body portion journaled in the casing, a thrust ring seated in the counterbored recess in the outer end portion of the barrel, a spindle extending through the casing and having a tapered portion journaled in the bushing, a body -port-ion journaled in the barrel and a reduced end portion extending through the counterbored recess of the barrel, the resultant shoulder of the spindle being in substantial alinenient with the bearing face of the thrust ring. a thrust sleeve journaled on the reduced portion-ot' the spindle and provided with an enlarged inner end portion bearing against the thrust ring and spindle shoulder, a thrust nut screwthreaded into the outer counterbored recess .of the barrel and adapted to bear against the outer face of the enlarged end portion of the thrust sleeve, a retaining nut on the outerreduced end portion of the spindle, and a transversely disposed binding stud in., the casing adapted to secure lthe barrel in adjusted position.

4. The combination of a casing having a substantially cylindrical bore with an inner peripheral screWt-hreaded rib bet-Ween its ends, of a taper bored bushing secured in one end portion of the casing, a barrel rotatable in the other end portion of the casing in screwthreaded. engagement with the inner rib thereof provided with a counterbored outer end, a thrust ring seated concentrically in the base of the counterbored recess in t-he outer end of the barrel, a spindle journaled in the tapered sleeve and barrel having a reduced end port-ion extending through the counterbored recess, a thrust sleeve journaled on the reduced por? tion of the ring having a flange on its inner endin abutment with the. thrust ring,` a thrust nut screwthreaded into t-he counterbored end portion of the barrel in abutment with the outer face of the thrust sleeve flange, a retaining nut on the reduced end portion of the spindle. and a clamping stem longitudinally adjustable transversely in the casing and bearing against the barrel laterally.

In testimony whereof I aix my signature in presence oi"l two witnesses.
